Determination of the Susceptibility of Silver-Plated Copper Wire/Cable to Red Plague Corrosion

摘要

An accelerated screening test method to determine the suitability of silver-plated wire/cable materials, for use on ESA spacecraft and associated equipment is described. The test method, which also determines the suitability of the related fabrication processes, is based on the work of Anthony and Brown (1965). The environmental test system artificially promotes red plague corrosion under controlled laboratory conditions as a result of galvanic corrosion of the copper conductor core in locations where breaks or porosity exist in the silver plating.
